BOTTLE AND BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 439,693, dated. November 4, 1890.

Application filed December 13, 1839- To all whom, it may concern:

Be it known that I, EUGENE M. SANGER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bottles and Bottle- Stoppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bottle-stoppers.

The object of the invention is to produce a bottle-stopper of such construction that the bottle may at all times be closely or hermetically sealed and escape of gases from confined liquid or of the liquid itself prevented under all circumstances.

With these objects in view the invention consists, essentially-in a bottle-stopper comprising a bottle-neck provided with a continuous indentation in its top and provided on the interior of its neck a short distance below the top with beveled and inclined lugs or projections, a stopper to be placed in the bottle provided with a corresponding indentation, and with a stem provided with alower conical portion elliptical in cross-section, the incline of the sides of the conical portion corresponding to the incline of the lugs.

I have illustrated the invention in the accompanying drawings, in which- Figure 1 is a sectional view of a bottle constructed in accordance with my invention. Fig. 2 is a side view of the stopper removed from the bottle, and Fig. 3 is a sectional view showing the construction of the neck of the bottle adapting it for reception of my stopper. Fig. 4 is an inverted plan View showing the shank of the stopper and illustrating the shape of the lower portion thereof. Fig. 5'is a section on the line mm of Fig. I, particularly showing the lugs on the interior of the neck of the bottle and the form of the conical lower portion of the stopper.

In the drawings, A represents the neck of the bottle, in the upper portion of which is a continuous channel or groove a, preferably circular in form. v

B represents the stopper of the bottle, which is preferably of glass, and is provided on its under surface with a continuous groove 1), the

parts being so arranged that when the stopper is in position the grooves a in the bottle and b in the stopper form three sides of a chamber, of which the fourth side is formed by the depending portion of the stopper which enters the bottle. In this chamber is placed a circular piece or ring 0, of cork or other suitable material, which when compressed will form a water-tight and practically airtight joint between the stopper and the bottle. By the construction of the parts it will be seen that the ring, being placed in the circular chamber, will be prevented from swelling or otherwise getting out of shape, and that escape of liquid or gas from this cause will be impossible.

The lower portion 1) of the stopper is made as shown-that is, tapering from a short distance below the main cap portion to a point W, from which point it enlarges and assumes a shape corresponding to the contour of the inside of the bottle in which it is to be placed.

On opposite sides of the bottle in which the stopper is placed and at a point adjacent to the flaring portion 11 of the stopper are inwardly extending inclined projections a. These flattened portions are preferably slanting, and as they are pressed into the neck of the bottle from the outside the diameter of the neck at that point is lessened. The lower conical portion of the stopper is elliptical in cross-section, thus presenting a suitable form for permitting the introduction of the stopper between the lugs and at the same time permitting of the fastening of the stopper in place by turning the longer portion to bring it under and in contact with the lugs.

By turning the stopper slightly the flaring portion of the stopper is brought into contact with the flattened portions, and as these are slanting the more the stoppers are turned the tighterit will be wedged.

By making the stopper of the form shown projections which are liable to become broken by pressure of tightening are avoided and a strong stem capable of withstanding pressure is provided'for bearing against the bottle in the act of tightening the stopper.

Having thus fully described my invention, what I claim as'new, and desire to secure to secure by Letters Patent, is-

The combination, with the neck of a bottle, provided in its upper face with a continuous indentation and on the interior of its neck a short distance below the top with inclined 5 beveled lugs, of a stopper provided on the lower face of its cap with n continuous indentation and having a stem provided near its lower end with a conical portion elliptical in cross-section, the incline of the sides of the 10 conical portion corresponding to that of the lugs on the interior of the neck of the bottle, and a ring of cork or the like interposed between the top of the neck of the bottle and the stopper substantially as described.

In testimony whereof I affix m y signature in :5 presence of two Witnesses.
